n. (abbrev. fruit + tube) obscure yogurt snack in an "easy-open" flexible plastic tube. sent under because it foolishly attempted to promote healthy eating amongst young children, and 50% of the time was unopenable by hand.

Eating a frube makes me feel like I'm giving a very sloppy, but delicious, blowjob.

A frube is a surfer who doesn't catch a wave for the whole time they are in the water.

Dude #1: The waves are so good! It's perfect!
Dude #2: Yeah dude! But that frube over there has been here for like 4 hours and still hasn't caught a wave!
Dude #1: Dude! What a frube!
Dude #2: Yeah dude! FRUBE!
